How do computer users protect their computers from too much electricity?

Answer 1

To protect a computer completely from electrical problems you would have to keep it unplugged. Unfortunately this makes it useless.

Using surge protection on the power supply is a simple and relatively cheap protection from spikes in the power supply. A UPS or uninteruptible power supply can be set up to allow the computer to run for a period of time after a breakdown in the power supply. These are more expensive the longer they can supply power, and are often set up to supply power for just long enough to do a save and tidy shutdown of the computer.

Answer 2

Unplug them from the mains and telephone lines during an electrical storm. If your house is hit by lightning, it will find the shortest path to earth - usually via the ring main. This will 'fry' any electrical devices plugged in (even if they're not switched on !)

Answer 3

Use a device called a 'surge protector'. They come in a variety of forms, from a single plug to replace the plug on your computer's power supply - to a multi-gang socket for up to eight devices. The surge protector 'cleans' the incoming mains electricity - making it more stable for the equipment attached to it. Additionally, it can protect equipment from power surges (spikes) by 'absorbing' the excess current & voltage.

Answer 4

Plug a surge protector into the wall and plug the computer into the surge protector.

Answer 5

A surge suppressor
